HI Susan,
1. This is written in a very standard HTML.
2. Here is the code we gave you last time:
function pojo24475_setup_builder_widget_args( $args ) {
$args['before_title'] = '<h2 class="pb-widget-title"><span>';
$args['after_title'] = '</span></h2>';
return $args;
}
add_filter( 'pb_empty_widget_args', 'pojo24475_setup_builder_widget_args' );
